(TUTORIAL) How to Make LiveCD/USB from installed Slackware 13/current or Arch system!

linus72 · 07-12-2010, 03:45 PM

lol
its cool
Yes, you must use Ritchie's modified LLS which uses squashfs 4.0 vs original LLS' squashfs 3.4

with 4.0, it builds the cd faster and somewhat smaller
I included it in /root

heres the thread with Ritchie's LLS
note that mine is even more modified than his
http://www.slax.org/forum.php?action...parentID=59545

the original LLS only did aufs/squashfs as module

I edited lls/initrd/initrd_create as so

line #142-154

Code:

#rcopy $ROOT/$LMK/kernel/fs/aufs $INITRD_TREE
#rcopy $ROOT/$LMK/kernel/fs/squashfs $INITRD_TREE

## Use the above if you have aufs & squashfs set as (M) modules
## Use the below if you have aufs & squashfs set as (y) or "built-in" to kernel

if [ -d $ROOT/$LMK/kernel/fs/aufs ]; then
rcopy $ROOT/$LMK/kernel/fs/aufs $INITRD_TREE
fi

if [ -d $ROOT/$LMK/kernel/fs/squashfs ]; then
rcopy $ROOT/$LMK/kernel/fs/squashfs $INITRD_TREE
fi

if you read the whole thread at Slax forum you'll see its a continuing concept...

You didn´t change anything else? Only initrd_create?

And I did compile "my own" kernel. That should not matter since I only changed the name of the kernel to 2.6.34-exton-slack. I e I used make oldconfig. (Used your .config).

linus72 · 07-13-2010, 06:19 AM

well
you mean different compared to original lls or whats different from ritchie's?

yeah, actually a whole lot has changed
from original lls
if you read Ritchie's post at Slax forum
it explains it all

http://www.slax.org/forum.php?action...parentID=59545

I also changed a couple things in Ritchies new one
namely initrd_create and
edited linuxrc and added at line 228,

Code:

mkdir -p $UNION/media

as originally lls doesn't create this folder
and thus pcmanfm would'nt mount drives etc without /media folder..

So, what happened so far?
did you read the readme thing?

For reference; since I started nFluxOS, I now have 6 Slackware installs including 1 x86_64, 6 arch installs including 1 x86_64,
and I haven't had one fail to boot as a liveusb, etc

you shouldn't have to do makeoldconfig as the .config in the linux-2.6.34 folder is exactly the same as the one in /boot
did you change anything in the kernel?
it has gobs of stuff in there huh?

I think if you just boot off the original kernel and run the build script it'll work fine
However, there's a couple scripts that need to be there for a livecd
namely /etc/rc.d/rc.slax for boot cheatcodes
and also /usr/bin/xconf and /etc/X11/gui.conf

so, tell me whats up?
make sure you change the aufs setting in kernel from max branches/loops 511 to 127, as it'l boot a little faster.

I did not change anything in the kernel.
My remaster using your LLS with "my" compiled kernel won´t boot. Kernel panic - not syncing: no init found is what I get.
Trying my remaster using your LLS with your original kernel give me the same result - kernel panic.

linus72 · 07-13-2010, 04:39 PM

OK
please tell me the exact procedure you used?
did you install the .txz or installed stuff manually?

what system is your host system? Slackware?
EDIT: are you doing this in a VM?

I installed the .txz.
I´m trying to remaster my Slackware 13.1 system, which I have installed to hard disk. (No VM).

linus72 · 07-14-2010, 02:14 PM

MMM
it works flawlessly in all of mine
as I said acroos 3 computers ...

and you do
cd into linux-live folder or open terminal there
then do
./build

right?
any errors during build?
does /tmp/live-live.log say anything?

did you try decompressing the .txz and manually installing everything?

Yes, I do it as I always do. (Run ./build etc).
No errors and no clue in linux-live.log.
I have not (yet) tried a manually install.

linus72 · 07-15-2010, 02:13 PM

OK
lets try and deduce if its the kernel or lls , etc

you can try using this kernel from superb-mini-server(was slack-mini-server)
http://sms.it-ccs.com/isos/SMS-Curre...plash_kernels/

get the livecd one, you gotta use Ritchies linux-live-6.3.0_x86 with this one too
and edit /etc/rc.modules after installing and uncomment what you want, processor, thermal, video, etc

I already have a kernel 2.6.33.3, which works. I have got it from you and I used it to make my version of nFlux, which I call exFlux. Please look here: http://linux.exton.net/node/487

What I want now is a working kernel 2.6.34.1 or 2.6.35 with aufs and squashfs as modules or built in.

linus72 · 07-17-2010, 06:22 AM

why did it double post?
Mod please remove one thx

hey golfer7
so, your in Sweden?

well, I'm working on the kernel how-to thing now...

I dont know why it wont work for you but I suspect something went wrong when I did makepkg on it or something..
so, I'm gonna tar everything up straight from the slackkware version I just uploaded
http://multidistro.com/NFLUXNEW/SQ4/slack.html

I'm gonna archive the kernel, modules, firmware, and the lls folder and you can download them
i'll include the kernel source too
it wont be a package, just tarred up
cool?

also, I installed the maverick meerkat daily build yesterday
and made a test cd of it
http://cdimage.ubuntu.com/daily-live/current/

it comes with 2.6.35-7 and it upgraded too 2.6.35-8 after install
when I made livecd of it

anyway, ubuntu puts some things in /lib/modules/ubuntu including the aufs module dont know why they put stuff there...?

check this out too; keep your ubuntu builds up to date
http://ansi.interblc.com/2010/02/06/...2-with-ubuntu/

my point being that you may be able to use ubuntu's new kernel
I know a way to create livecd from installed system by using livecd/usb, copying livecd/usb kernel, modules, and lls to host system and run lls
doesn't matter what kernel installed system has

so, I guess I goota write howto now...

Yes, I live in Sweden.

So your new "livecd" kernel for Slackware 13.1 will be 2.6.35.8 then? Very cool in that case.

In the meantime I have made a new remaster of Slackwrae 13.1 with Gnome 2.30.2 using kernel 2.6.33.3. I will replace that kernel with your new kernel 2.6.35.8 asap. That will be something...

Thanks again for all your work.

linus72 · 07-17-2010, 07:58 AM

hey golfer7
dang it that must be nice having all those 6-foot tall blond swede babes around huh?!
lol
(sigh...)

OH,
I meant I was gonna try to implement the 2.6.35-8 kernel
dont know how successful that might be....
heres meerkats source
https://launchpad.net/ubuntu/maveric...35/2.6.35-8.13

strangely aufs is in linux-source-2.6.35/ubuntu ?

today I'm jammin the heavy metal and messin with stuff...you know

heres the kernel I used in newest slackware iso; 2.6.34-ZENs32, modules, source, firmware,
all the slax stuff and /root/lls
http://multidistro.com/Kernels/zen1-...olfer7.tar.bz2

Now, you gotta manually make symlinks for vmlinuz, config, System.map
rc.modules and rc.M

ln -s vmlinuz vmlinuz-2.6.34-ZENs32
etc, etc
you know right?
and choose either rc.M-live or rc.M-std, rc.M-live just boots a little faster...
cd /etc/rc.d
ln -s rc.M-live rc.M
so, make the symlinks for vmlinuz,config,system.map, /etc/rc.d/rc.modules, /etc/rc.d/rc.M
and thats it I think...

EDIT: compiling meerkats source now on my -current slack setup...
I made aufs as built-in so that will get around the ubuntu folder issue I think...

I just booted off of zens32 kernel and did

Code:

zcat /proc/config.gz > .config
make oldconfig

and then fixed it up
and did make menuconfig....

I usually use Alien's kernel instructions
http://alien.slackbook.org/dokuwiki/...kernelbuilding

linus72 · 07-17-2010, 05:26 PM

Well
here's the good, the bad, and the ugly

the good:
kernel 2.6.35-rc5 compiled after I had to unselect some of the ubuntu stuff in menuconfig
and I successfully booted off the kernel and all seemed ok

the bad:
I ran lls build successfully; however, when trying to boot it said the modules(bin.lzm,etc.lzm, etc) were corrupt, etc
and some other erros...

the ugly:
the errors mean that Meerkat's using a higher squashfs than in Ritchie's LLS which uses 4.0 or 4.1
so, maybe theres a way to build the higher squashfs or wait...
I gotta check something
